PROCESS AND MACHINE FOR MARBLEIZING PAPER AND THE LIKE.

Specification of Letters Patent.

Patented Oct. 5, 1909.

Application filed January 15, 1908. Serial No. 410,887.

To all whom it may concern:

Be it known that I, Hmxmcn Murzonu, a subject of the Emperor of Germany,and resident of Aschalfenburg-Damm, Bavaria, Germany, have inventedcertain new and useful Improvements in Processes and Machines forMarbleizing Paper and the Like of which the following is aspecification.

My invention relates to the marbleizing of paper, card board and thelike, particu larly in the form of a continuous web, and has for itsobject to carry out such treatment efficiently and expeditiously.

Other objects and features of my invention will appear from thedescription following hereinafter.

Reference is to be had to the accompanying drawings, in which Figure 1is a side elevation of a machine suitable for carrying out my invention;Fig. 2 is a vertical section on line A-B of Fig. 1; and Fig. 3 is a planview.

The machine has a frame a resting on legs a and supporting the supplychannel I). This channel has a cross flange at its rear end and alsolongitudinal side flanges, but is open at its forward end so that themarbleizing fluid (for instance water) may run off at such forward end,to drop into an in clined discharge channel 0. The supply channel ispreferably inclined in the opposite direction and its inclination may beadj usted in any suitable manner. Thus in Fig. 1 the rear end of thechannel I) is pivoted at b and the front end has secured to itperforated lugs or nuts b into which screw threaded rods 6 so carried bythe frame as to be capable of rotation but not of vertical movement. Theshaft 6 which may be turned by means of either one of the handwheels I),is suitably geared to the rods 0 to operate them both. To relieve theadjusting mechanism of undue strain, I have connected a counterweight(pivoted on the frame at 6 with the central portion of the channel I),by means of links I)".

At the front end of the channel I), which is generally its upper end, Ilocate the distributer d for marbleizing fluid. This distributer may bea simple overflow box combined with a pipe d applying a continuousstream of said fluid. The latter overflows into the channel I) and flowstoward the open rear end of the same, forming a thin sheet or film onthe bottom of the channel. The

"flanges of the channel would compel the fluid to seek the open lowerend, even if the channel were perfectly horizontal, but in practice thechannel will generally be inclined more or less. Near the front end ofthe machine are located brackets c carrying the guide roll arrangedslightly above the liquid film, said roll being preferably adjustablevertically as by means of screws f, so that its position may be variedto correspond to the adjustment of the supply channel I). The brackets 0also support the paper roll 9 and a guide roll 2'. The paper passes fromthe roll 5 to the roll then to a roll I), journaled on the frame, andfinally to the roll 2'.

While the marbleizing liquid is on its way to contact with the paper atthe roll I apply to such liquid the marbleizing colors and distributethem. This may be done by hand or by means of mechanical devices. Thus Ihave shown spray-heads Z for discharging the colors on to the surface ofthe liquid film in the channel I), and between said heads and the roll 7I have arranged movable combs m and stationary combs 'n for distributingthe colors on the film and forming them into designs. Any suitablecolors may be employed, including oil colors.

The parts are so adjusted that the surface of the paper just touches thesurface of the liquid, that is, the paper does not dip into the liquid.The surface of the liquid being tangential to that of the paper, contactoccurs practically only along a single transverse line. The colorsfloating on top of the liquid adhere to the paper and are carried awayby it. As the liquid sheet or film is comparatively thin it flowsevenly,without eddies, and there is therefore but little disturbance (if any)of the designs into which the colors have been formed. As the paper doesbut touch the surface of the film, it does not materially retard theflow of the liquid, and I thus avoid distortions of the designs whichmight be caused by a backing up of the liquid. The paper takes but aminimum of moisture, and thus the colors will not run on the paper evenshould it rise vertically from the roll The liquid arriving at the rollf is always absolutely fresh, as the used or spent liquid is drawn offat the lower end of the channel Z).

. port. applying color to the The paper with the marbleized designsthereon may be sprayed with a suitable liquid (as indicated at to cleanand fix the colors. The surplus liquid dripping off at' this point maybe collected separately, or run together with the spent marbleizingliquid. Finally the paper would be dried in any suitable manner.

By varying the inclination of the channel I), the velocity of themarbleizing fluid can be adjusted, so as to vary the designs produced;such variation is also obtained by operating the combs m differently.

The process and machinedescribed above may be employed in connectionwith plain or colored or printed paper, cardboard, paste-board or thelike.

I claim as my invention:

1. The herein described process of marbling paper and the like. whichconsists in causing a thin film of a readily movable liquid to flowbodily on a stationary support, applying color to the surface of saidflowing film, and bringing only the surface of the paper in tangentialcontact with the color on the moving film, to transfer such color fromthe film tothe paper.

2. The herein described process of marbling paper and the like, whichconsists in causing a thin film of a readily .movable liquid to flowbodily on a stationary supfiowing film, bringing only the surface of thepaper in tangential contact with the color-on the moving film totransfer such color from the film to the paper, and spraying a liquidagainst the marbled side of the paper after it has come out of contactwith the film.

3. In a machine for marbling paper and. the like, an inclined supplychannel, a dis-- charge channel arranged below the supply channel andinclined in'the opposite. direction, a paper guide located slightlyabove the supply channel adjacent to its lower end, and means forsupplying a marbling liquid at the upper channel.

4. In a machine for marbling paper and the like, an inclined supplychannel, a paper guide located slightly above said channel adjacent toits lower end, and means for supplying a marbling liquid at the upperend of the channel.

5. In a machine for marbling paper and the like,

a supply channel pivoted at one surface of said plying a marblingschannel, a-pa'per guide located ad acent to end of the supply end sothat it may swing up or down, adjusting mechanism connected with theother end of said channel, a paper guide located slightly above thechannel adjacent to its adjustable end, and means for supplying amarbling liquid at the other endof the channel.

6. In a machine formarbling paper and the like, a supply channel pivotedat one end so that it'may swing up or down, adjusting mechanismconnected with the other end of said channel, eounterbalancing meansconnected with the central portion of the channel, a paper guide locatedslightly above the channel adjacent to its adjustable end.

andmeans for supplying a marbling liquid at the other end of thechannel.

7. In amachine for marbling paper and the like, an inclined supplychannel, means for adjusting its inclination, a paper guide to its lowerend, and means a marbling liquid at the other end of the channel.

8. In a machine for marbling paper and the like, an inclined supplychannel, means for adjusting its inclination, counterbalancing meansconnected with the channel, a paper guide located slightly above thechannel adjacent to its lower end, and mcans for supplying a marblingliquid at the other end of the channel. v

9. In a machine for marbling paper and the like, a supply channel, meansfor supliquid at one end of said the otherend of the channel andslightly above the same, color-distributing means located above thechannel between its ends, .and means for spraying a liquid against themarbled side of said guide.

10. In a machine for marbling paper and the like, a supply channel,means for supplying a marbling liquid at one end of said channel, apaper guide located'adjacent to the other end of the channel andslightly above the same, and means for spraying a liquid against themarbled side of the paper after it has left said guide.

In testimony whereof I have hereunto set my hand this 2nd day of January1908.
